RACK.

Specification of Letters Patent. Patented BT31; 30, 1920.

Application filed. October 17, 1919. Serial No. 331,270.

To all whom it may concern:

Be it known that I, JOHN T. Tron, a citizen of the United States, residing at West Point, in the county of Troup and State of Georgia, have invented new and useful Improvements in Racks, of which the following is a specification.

My present invention has reference to calendar racks for picking machines in tex tile mills and is of a substantially similar nature to my pending application Serial No. 298,156, filed May 19, 1919.

The improvement contemplates the employment of a calendar rack having at its upper end a laterallyextending fixed head portion to. which is pivotally secured a hollow movable head portion, the latter having a depression or pocket to receive the lap pin of a picking machine and anti-frictional rollers which contact withthe said pin, the fixed head being provided with a pivoted archedmember that contacts with the outer face or top of the movable head for'retaining the movable head in proper position on the fixed head. the said arched member being held in such contacting engagement with the movable head-through the medium of a fragile element connected to both the arched member and to the fixed head, the construction beingsuch that when excessive pressure is exerted by the lap pin against the pivoted head the fragile member will become broken. permitting the pivoted head member and the arched contact member being swung rearwardly upon their respective pivots, so

that no injury, other than the breakage of the fragile member will result to either .the calendar rack or to the parts of the picking machine which might otherwise be seriously injured and which, incident to the flying parts caused by such injuries might result seriously to the operator or to others in close proximity to the machine. 7

Other objects and advantages will present themselves as the nature of the invention is more fully disclosed. reference being had to the accompanying drawings, in which:

Figure l is side elevation of the improvement. 7 Fig. 2is a front elevation thereof. Fig. 3 is a sectional view approximately on the line 3-3 of Fig. 2. r

Fig. 4: is a perspective viewiofthe movable member of the head. r

Fig. 5 is a perspective view of the upper portion of the rack having the fixed head. Fig. 6 is a perspective view of the arched member which is pivoted to the outer end of the fixed member of the head and which engages with the movable member of the head to hold the same in fixed position on the fixed member of the head.

Fig. is aperspective view of the fragile connecting member between the arched contact member and the fixed member or section of the head. My improved calendar. rack includes the usual shank 10 having its outer edge provided with the usual teeth 11. The shank at its upper end is integrally formed with a head section 12. This head is substantially V-shaped in side elevation, the lower wall of which being arranged at a right angle with respect to the shank, the front wall being preferably slightly dished, and the upper or rear wall being arranged at a right angle with respect to the shank, the front wall being preferably slightly dished, and r the upper or rear wall being disposed substantially at a right angle with respect to the lower wall. The fixed head 12 is of a greater thickness than the shank 10, and the upper or rear wall thereof, indicated for distinction by the numeral 13 has atits 'outer end upstandingears 1a -which are flush with the sides of the head section. In

addition to this, the said top or rear wall 13v adjacent to the front concaved wall-15 of edge thereof opposite that provided with section, it will be noted, projects laterally from the shank in a direction beyondthe the teeth 11, which is an important feature of the invention, inasmuch as the weight of the said head will resist the pressure exerted by the toothed wheels on the. picking machine which engage between the teeth and is consequently tend to preventan outward or lateral swinging of the calendarrack. 1" The movable head section for the calendar rrack is broadlv -.indicatedby the: nu-.

meral v17, the same'includingan upper solid body portion 18 which is provided'with .de-

pending sides or flange portionsil!) thatex-Q V I tend'a suitable distancebeyond the rear: of I the body. It will be noted, by reference to the drawings that the rear portion of the movable head is substantially V-shaped in side elevation, corresponding in shape to that of the fixed head section. The movable head section has its upper corner rounded and its outer face straight. The side mem-" bers or flanges are so spaced. as to be arranged over the sides of the fixed head section and the said sides are pivotallly connected to the outer end of the said fixed head section, as indicated'by the numerals '2(). The lower edge ofthe sides 19 are disposed flush with the I lower straight face of the fixed head, and the shank 10 at its juncture with thefixed head is provided with out standing members or lugs 21 which, contacting with the lower edges of the side menibers 19 limit the swinging of the movable headsection downwardwith respect to the fixed head section. The side members out ward of the shank are provided withinwardly extending rounded depressions22 arranged in opposite alinement and the lower corners ofthe said sides .19 are round ed as at 23. These last mentioned'rounded portions may be termed lips, and between these said lips there is arranged an antifrictional roller 24 that has its ends pro vided with trunnions that find bearings in openings in the lips, A similar roller 25 having its ends also provided with trun nions received in'suitable bearing openings infthe sides 19 isarranged to have its lower periphery project slightly in the depressions 22. The ends of the lap! pin around which the cotton lap is wound find hearings in the depressions 22 and are contacted by the anti frictional rollers 24""and 25, it being understood that twoofsuch' racks are employed, and as the.

construction" and arrangement of the calendar racks on a spinning machine and the construction and cooperation of the lap pins witirthei calendar warheads are likewise so wellknowlr in'th'e art, the illustration thereofhas' not been deemcd'necessary.

Pi'otally secured,as at between the ears 14: andKthe fixed head section is an aijclie'd fmember 27 that has its outer end 28' flat to" provide afirm contacting surface tacti'n'g position with the movable member ofthe" head. The'membe'r 30, in; order to rendenthe same more fragile is centrally re duced, so that t lie,sameprovidesa reciprocatory neck portion 31 that connectsthe ingof the lap pin of the calendar head and prevent the lap plll'flOnl bearing outward or hanging on the main frame of the picker machine. I

'From the foregoing description, when taken in connection with theTlr'aWingS, it

will'be apparent'tothose skilled" in the; art

to which this invention appertains that an excessive pressure of the. lap pin against its hearings in the movable headsection of the calendar rack will cause the breakage of'the fragile element 30,ithus'relieving the arched contact memberfrom its fixed engagement with the fixed head section, and permitting the; movable head [section to swing rearwardly on the fixedhead section,

so'that no injury, other than the'breakage of the fragile element will result to either the calendar rack or to the parts of the machine to whichit is connected; Whenthe excess of pressure has'been removedor re lievedthe pivoted ormovable section of'the head of the calendar rack may be swungto operative position and a' new fragileelement may connect'the arched cfo'nt'act'member for thepivoted head section to'the' fixed head section, and the working of the machine will be only slightly delayed. Otheradvantages of a calendar rack constructed with a fixed and movable head section havebeen fully set forth: in my referred to I co-pending application Serial 'No; 298,156, filed-'May 19,

is not here deemed necessary. 7

Having thus described 'the invention, what is claimed, as new, is i p 1. A calendar ra'cli'having a laterally extending fixed head portion and a movable 7 headsection pivotally secured to the" fixed head" section and projecting in an opposite direction from said fixed head section, a pivoted meinb'er on the fixed head'se'ction contacting with the movable head section for; retaining the latter in one position, and abreakable element between said Tpivoted element and the fixed head 'sectionfor retain ing the latter in engagement with the mov- 1 able head section except when an? excessive 191'9jsofthatja detailed enumer'ationthereof pressure is exerted upon'the'latt'er in one daemon: V p

2. A calendar raclh'aving a" pivoted head section at the upper end thereof: a pivoted overlying element contacting withthe' sec tion for holding the section in one position on the rack, and a breakable element connected vith said overlying element and the rack for holding said first mentioned element in contacting engagement with the pivoted head section.

A calendar rack having a laterally extending fixed head section, a hollow head section providing a bearing pivotally secured to the fixed head section and extending in an opposite direction therefrom, a pivoted element on the fixed head section contacting with he movable head section for holding the same in one position with respect to the fixed head section, and a fragile element connected to the pivoted element and the fixed head section for holding the said first mentioned element in contacting engagement with the pivoted head section.

a. A calendar rack having a laterally ex tending substantially V-shaped head provided with spaced pairs of ears upon the outer and upper portion thereof, a movable head section including a body having depending sides which extend to the rear thereof and straddle the fixed head and are pivotally secured to the said fixed head, said depending sides, outward of the rack having alining curved depressions providing a hearing opening, anti-frictional elements carried by the sides and projecting into the bearing opening, an arched member pivotally secured to the rear pairs of ears on the fixed head section and contacting with the upper face of the pivoted head section, depending ears upon the arched member, and a fragile element pivoted between these ears and the second pair of ears on the fixed head for holding the arched member in contacting engagement with the pivoted head.

In testimony whereof I affix my signature.
